Question

Find the value of P in the following addition

3 1 P

+1 P 3

______

5 0 1

• A. 8
• B. 9
• C. 7
• D. 6

Answer 1

The correct option is A

8

Let us look at the ones place first:
We know that P is a single digit number which when added to 3 gives a result with 1 in the ones place.
For ones digit, 3+ 8 = 11 $\Rightarrow$ P = 8 and 1 is carried over.

To Verify:
For tens digit, 1(carried over) + 1 + 8 = 10

For hundreds digit, 3 + 1 + 1(carried over) = 5
Hence:

3 1 8

+1 8 3
______

5 0 1
